A drop hammer of mass 120 kg falls 2.5 m onto a pile of mass 250 kg and drives it 70 mm into the ground. Calculate: The velocity with which the hammer strikes the pile (use the conservation of energy principle) The velocity immediately after the impact(use the conservation of momentum principle, assuming the hammer does not rebound on impact) The average ground resistance (use work-energy method)
A6.0 kg disk traveling at 9.0 m/s strikes a 7.0 kg stick of length 5.0 m that is lying flat on nearly frictionless ice as shown in the overhead view in the figure below. The disk strikes at the endpoint of the stick, at a distance r = 2.5 m from the stick's center. Suppose that the collision is perfectly inelastic so that the disk adheres to the stick at the endpoint at which it strikes. The moment of inertia...
